Thanks for the quick fix previous issue, but suddenly I found another one :,(

When I putting my resourcepack in conig/openloader/resources/RESOURCEPACK it name appears like "resources/RESOURCEPACK" not just "RESOURCEPACK" and, I bet, this is why RespackOpts can't find configuration file for that

Issue fixed in 20.0.5
